Re-Calibration Instructions
This Pocket Dial Thermometer can be re-calibrated should it be subjected to shock or extreme temperature changes.
To re-calibrate to within ± 1 division, immerse the stem at least 3″ into a slush ice solution (60% crushed ice and 40% tap water). Wait at least one minute for the sensor to reach equilibrium. By holding the unique, hand calibrating nut in one hand, the Thermometer can be adjusted until the pointer reads 32°F, as shown below.
